Buchert Audio has introduced a free stereo width plugin for macOS, available in AU and VST3 plugin formats.
Offering simple stereo width control with a single knob, The Double Wide lets users narrow their mix for focused mono compatibility, or widen for an expansive stereo field.
Turn left to narrow. Turn right to widen. The plugin handles M/S encoding, bass protection, and smoothing automatically.
The Double Wide is free to download from the Buchert Audio website.
